When a Lagiacrus is fully sunbathed, it turns a dry grayish-blue color and its dermal spikes turn brown. When it returns to the water, Lagiacrus regains a striking deep blue color and its spikes return to their original color of a very light beige.

Abilities

The dermal spikes on its back glow white when it is using strong thunder attacks, and its mouth gurgles with Thunder when it is enraged.

Monster Hunter Stories

Leviathans atop the aquatic food chain, due in no small part to their ability to deliver electrical shocks.

Lagiacrus is the first Leviathan of its kind to be encountered in Monster Hunter 3.

When encountered for the first time offline, in the 1* Village Quest: "Guts- It's What's for Dinner"; Lagiacrus cannot be killed. Its body parts can be broken, and its tail can be carved, but it will only go as far as limping, and cannot be killed until the Urgent Quest in the Village.

When present in Deserted Island , Lagiacrus will, on rare occasion, leave the water and venture no further inland than Area 5.

Even if the Lagiacrus' tail is cut or its parts broken in the "Trial of the Sea Dragon" urgent quest, it will return in "Fell the Lagiacrus" healed and unwounded.

The Lagiacrus is one of the only two monsters in Monster Hunter Tri to have a weapon in every category. The other is Alatreon.

Lagiacrus uses a drastically different set of electrical attacks to compensate for the removal of underwater combat.
